A REVIEW ON THREE PHASE GRID CONNECTED PV SYSTEM USING THREE LEVEL CASCADED H BRIDGE MULTILEVEL INVERTER

Abstract

In the recent trend of using green energy, grid connected Photovoltaic (PV) systems are getting more popular. This paper aim to review on, multilevel inverter based single-stage grid connected photovoltaic system based on cascaded three-level inverter is carried out using MATLAB/Simulink. The inverters are controlled using hysteresis current controller for which the synchronizing reference currents are generated using d-q theory. The maximum power is extracted from the PV array under varying environmental condition. The cascaded three-level inverter based grid connected PV system is simulated for injecting active power produced by the PV array under varying solar insolation.
